BIOL 1309 Chapter 14 Study Practice Test. population - CORRECT ANSWER A group of individuals of the same species that live in the same area and interact with one another is a speciation - CORRECT ANSWER The process that gives rise to new species is called reproductive barrier - CORRECT ANSWER is anything that prevents successful interbreeding between species. biological species concept - CORRECT ANSWER defines a species as a group of populations whose members have the potential to interbreed with one another and produce fertile offspring. Which of the following examples uses the biological species concept to describe different species? - CORRECT ANSWER Female horses and male donkeys are able to mate, but their offspring (mules) are infertile. Behavioral isolation prevents different birds-of-paradise species from mating and reproducing. Which of the following describes a behavioral isolation reproductive barrier? - CORRECT ANSWER Males of one species perform orchestrated dances and sing songs that only attract females of the same species. Habitat isolation - CORRECT ANSWER Two populations of lobsters do not mate because one population lives in the Atlantic Ocean and the other lives in the Pacific Ocean. Gametic isolation - CORRECT ANSWER Many populations of clams release their sperm and eggs into the same region of a lake, but only the sperm and eggs from the same species successfully unite to form zygotes. Mechanical isolation - CORRECT ANSWER A male snail and a female snail from different species attempt to mate, but the orientation of their different types of shells prevents mating from occurring. Temporal isolation - CORRECT ANSWER Two populations of flowers do not produce offspring because one blooms during early spring and the other blooms during late spring. Biological Species Concept - CORRECT ANSWER based on reproductive isolation caused by prezygotic & postzygotic barriers. Morphological Species Concept - CORRECT ANSWER based on distinct body structures. Allopatric Speciation - CORRECT ANSWER in which gene flow is interrupted between geographically isolated populations. Sympatric Speciation - CORRECT ANSWER in which gene flow is interrupted due to polyploidy, habitat differences, sexual selection. Hybrid Zones - CORRECT ANSWER which may results in fusion of species, stable hybrid zone, and reinforcement of reproductive barriers. Example of Sympatric speciation - CORRECT ANSWER Self-fertilization in plants allows a new species to arise amidst the ancestral population
